As shown in the detail view, the end faces 12a of the rods 12 are set back slightly from the outer sides 11a of the belts 11 so that the end portions 13 of the rods are fully enclosed thereby minimizing the risk of damage to crops or to the machinery from sharp corners and edges on the ends of the rods. In order to reduce the risk of damage to the belts 11, these may also conveniently have included therein a steel mesh layer 19 or the like just below the outer face 20 of the belt 11 in order to provide a barrier to sharp-edged stones or the like cutting into the belt 11.
